Product Overview

The Emerson KJ4110X1-BC1 (Part Number 12P1869X012) is a specialized 16-channel digital input terminal block designed for the DeltaV™ M-series I/O Subsystem. This module serves as the primary physical interface between field-side discrete devices—such as proximity switches, limit switches, and push buttons—and the DeltaV Distributed Control System (DCS). By providing a secure, organized termination point for 16 individual signal paths, it ensures high-fidelity data acquisition and seamless signal routing to the corresponding I/O cards.

The KJ4110X1-BC1 is engineered to simplify wiring complexity while maintaining the high availability required for modern industrial automation. It facilitates rapid installation and maintenance through its modular design, allowing for the quick connection and disconnection of field signals without disrupting the broader system backplane.
